One thing to add is that there is no guarantee this is even against the German constitution.

Local devices only scanning which only if there is an issue sends any information to anywhere outside of the device might actually be compatible with the German constitution by the argument that the privacy is only violated if the local validator phones home and that it only does so if there is a reasonable suspicion at which case it isn't baseless mass surveillance anymore... on a technicality iff the local scanner have close to now false positives. It's anyway a bad idea and a lot of the things it claims it's meant to help with have a lot of neglected other solutions which would improve things a lot.
